Radial vibration measurement sensor calibration device

Abstract

The invention discloses a radial vibration measurement sensor calibration device comprising an L-shaped fixing frame and a micrometer head support. The long arm ends of the fixing frame and the micrometer head support are horizontally arranged. The two sides in the length direction of the top end of the fixing frame are provided with parallel pressing plates. The long arm end of the micrometer head support is arranged between the side walls of the two pressing plates. A hand wheel penetrates through the micrometer head support and then is fixed with the fixing frame. A direct feed micrometer head penetrates through the short arm end of the micrometer head support and then is connected with a head clamping component. The head clamping component is connected with one end of a connecting frame. The other end of the connecting frame is provided with a sensor. The sensor penetrates through the short arm end of the fixing frame and a test installing plate. The short arm end of the fixing frame and the test installing plate are fixed. According to the radial vibration measurement sensor calibration device, the problems caused by aging of a spring in the conventional structure can be avoided, and the device has fast feeding and limiting functions so that use convenience and reliability of the calibration device can be greatly enhanced.

Description

technical field [0001] The invention belongs to a calibration device, in particular to a calibration device of a radial vibration sensor. Background technique [0002] In the radial vibration test, it is necessary to use a vibration sensor, that is, an eddy current displacement sensor. Before the test, the vibration sensor needs to calibrate the gap voltage curve of the sensor to obtain the sensitivity required for the vibration test. Because the sensor will be affected by many factors Therefore, the sensor calibration work must be done on site, so a device is needed that can change the gap between the sensor and the test piece to complete the calibration work. [0003] The existing device uses a conventional differential head. Although it can complete the calibration work, because the conventional differential head is working, the measuring rod will be accompanied by rotational movement when it moves linearly. Therefore, the original structure is designed to use a spring to...

Problems solved by technology

[0003] The existing device uses a conventional differential head. Although it can complete the calibration work, because the conventional differential head is working, the measuring rod will be accompanied by rotational movement when it moves linearly. Therefore, the original structure is designed to use a spring to connect the differential head. With the sensor, when the spring ages, there will be poor rebound, resulting in a decrease in the accuracy of the calibration structure, and there is no effective way to improve the existing structure
